How to add Header Content-type to static pages which doesn't have extensions?

I have a XML page www.example.com/page, but my server 开发者_如何学Gooutputs it as text/plain as it doesn't have any extension.

So I want to add XML Header via .htaccess to all the files which doesn't have extension with a condition that the file exists. As if file doesn't exist, program is executed from database and it decides what header to output, so I don't want to break that part by forcibly changing header.

Add a DefaultType text/xml (or whatever type you're using for your XML) to your .htaccess.

Other command you can put in your .htaccess (but it will force all files to have this content-type):

ForceType text/xml
